Spazio e sostenibilità: una sfida globale oltre l’atmosfera | Pierluigi Di Lizia | TEDxSaronno
TEDx Talks· 2025-07-25 16:49
[Musica] Esiste un mondo che non riusciamo ad osservare appieno con i nostri occhi, un mondo affascinante per la sua profondità e allo stesso tempo importante per la nostra vita quotidiana. anche se non ce ne rendiamo pienamente conto. Un mondo che come tale vogliamo e dobbiamo preservare.Qualcuno forse pensa al mare, ai suoi meravigliosi abissi e all'importanza che ha per la vita sulla terra o per le sue prossime vacanze e per questo con il pensiero sta volgendo lo sguardo verso il basso. Invece no. Io vi ...

Environmental Impact of Hexavalent Chromium - Hexavalent chromium (chromium-6) is a potent carcinogen found in industrial productions like metal finishing, contaminating water, air, and soil [4] - Traditional chromium-based processes generate approximately 30% waste, requiring energy-intensive recycling, resulting in a significant carbon footprint [10] - The company's alternative solution reduces energy consumption by over 25% [8] - Life Cycle Assessment (LCA) indicates the company's solution has an 80% lower carbon footprint compared to traditional chromium electroplating [11] Innovative Solution - The company has developed an organic and inorganic compound made from glass, utilizing cold vitrification to eliminate the use of hexavalent chromium [7] - The developed compound is non-toxic and 100% recyclable [8] - The solution has been tested on a large scale with significant companies, demonstrating improved performance compared to chromium-6 [9][11] Societal Impact - The story of Erin Brockovich highlights the devastating health consequences (malformations, tumors) of hexavalent chromium contamination on communities [4] - The company's innovation aims to enable factories to eliminate toxic emissions and protect public health [12] - The company's goal is to transform existing chromium electroplating facilities into greener operations, preserving jobs [8]
ECONOMIA CIRCOLARE: DAI BORGHI ALL'ASTRONAVE TERRA | Giuseppe Landolfo | TEDxLatronico
TEDx Talks· 2025-06-27 15:35
[Musica] Immaginate di essere su una navicella spaziale in viaggio verso Marte o verso un altro pianeta lontano. All'esterno della navicella solo il silenzio dello spazio. All'interno pochi compagni di equipaggio che galleggiano qui e lì, poche scorte, poche risorse limitate e un'unica missione, quella di tornare a casa sani e salvi. Per farcela non potrete permettervi sprechi, non ci saranno rifornimenti esterni. Per farcela dovrete riutilizzare tutto quello che c'è a disposizione sull'astronave. ogni cosa ...
La forza delle azioni per città più sostenibili | Luca Jaspreet Singh | TEDxHensemberger Youth

[Musica] La Terra è un pianeta straordinario. Tra miliardi di corpi celesti è l'unico che conosciamo in grado di poter ospitare la vita. La giusta distanza dal Sole, l'atmosfera che lo protegge e l'acqua in forma liquida.Elementi essenziali per la nostra esistenza. There is no planet B. Non c'è nessun pianeta B.Eppure sembra che questa espressione non ci faccia riflettere abbastanza. Dall'epoca preindustriale la temperatura media della Terra è aumentata di circa 1°. Se si decidesse di non agire entro il 205 ...
La Vera eredità del vino | Nicola Biasi | TEDxPisogne
TEDx Talks· 2025-06-18 16:30
Wine Industry Analysis - The wine industry acknowledges that winemaking is not sustainable and contributes significantly to pollution, including CO2 emissions and water usage [3][6] - Many wineries claiming sustainability may be misrepresenting their practices [3] - Over-reliance on tradition and heritage can hinder innovation and growth in wineries [4] - Viticulture is a science essential for producing quality grapes, which are fundamental to making good wine [5] - Achieving environmental sustainability requires economic sustainability for wineries to invest in quality and research [6] Environmental Impact & Solutions - Traditional viticulture practices are environmentally impactful, with concerns over CO2 emissions (2 tons per hectare) and water consumption (6,000 cubic meters per hectare annually) [8] - Resistant grape varieties can significantly reduce CO2 production (by 38%) and water usage (by 70%) in vineyards [14][20] - Innovation in viticulture, particularly through resistant varieties, offers a path towards more sustainable winemaking [11][12] Innovation & Legacy - Franco Biondisanti's pioneering work with Sangiovese grapes revolutionized Brunello production in Montalcino [17][18] - The ability to innovate is a more valuable legacy than material possessions or established practices [19][22] - The industry aims to leave a positive impact on future generations by promoting innovation and sustainable practices in winemaking [20][22]
Oro blu e raggi cosmici: creare sostenibilità misurando l’invisibile | Luca Stevanato | TEDxPadova

Water Resource Management & Agriculture - FAO warned over a decade ago that optimizing water use, especially in agriculture where over 70% of human water consumption occurs, is crucial to ensure food production for 10 billion people by 2050 [1] - The company's technology helps farmers use less water while increasing crop yields [7] - In Veneto, Italy, if the technology were universally adopted, approximately 120 million cubic meters of water could be saved each summer, equivalent to the city of Padua's water usage over 5 years [14] Technology & Innovation - A research group in the US and the University of Padua discovered elements to solve the problem of managing unseen underground water 15 years ago [2] - The technology utilizes cosmic rays, specifically neutrons, to measure soil moisture; neutrons are absorbed by hydrogen in water, allowing the device to indirectly measure water content [8][10][11] - The device, resembling a ping pong paddle, measures water content in an area of over 5 acres (approximately 250 meters in diameter) up to 50 cm deep when installed 2 meters above ground [12][13] Environmental Impact & Sustainability - The technology aids in identifying water leaks in cities without excavation, facilitating faster repairs and infrastructure investment planning [8][14] - The company measures Snow Water Equivalent (SWE) to help governments and organizations manage water resources, deciding when to store or release water in lakes and rivers [15][16] - Nuclear physics research from 15 years ago has become the foundation for a sustainability solution, preserving water resources [17]
